SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 684,318, dated Qctober 8, 1901.

Application filed June 26, 1901. Serial No. 66,068. (MocleL) To all whom it may concern.-

Be it known that I, JAMES C. SERGESON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Shuttles, of which the following is a specification.

My invention consists of a shuttle provided with means for locking the head of the spindle on the axial pin thereof, while readily allowing the displacement of the spindle when so required and not interfering with the motions thereof.

It also consists in constructing the spring jaws or clamps for the bobbin'or cop-tube whereby a bed is formed on which a member of the spindle-head is permitted to ride in the motions thereof, avoiding direct contact with the body of the shuttle.

Figure 1 represents a plan view of a shuttle embodying my invention. Fig. 2 represents a plan View of a portion thereof, showing the locking feature of the spindle-head in a different position from that shown in Fig. 1. Fig. 3 represents alongitudinal section on line :0 00, Fig. 2. Fig. 4 represents a transverse section on line y y, Fig. 2. Fig. 5 represents a perspective view of thespring jaws or clamps of the shuttle detached.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the body of the shuttle, in general respects of usual construction.

B designates the spindle, and O the head thereof, the latter having on its under side the heelD and the open slot D, through which latter is passed the axial pin E, and on its back the recess D to receivethe bearingpiece F, which is pressed against the head 0 by the spring G for holding the spindle in operative position.

H designates the clamps or ear-clips, whose jaws are adapted to engage with the bobbin or cop-tube on the spindle B to prevent displacement of said bobbin or tube when in operative position. The ends of the shanks of said clips toward the nose of the bobbin are connected by the transversely extendin g plate J, which serves to form a firm and rigid connection for said shanks and prevent them from closing on each other, so that the head 0, which occupies the space between said shanks, is prevented from binding or jamming with the latter. The tendency of the spring G is to press upwardly against the back of the head 0, and thus throw down the spindle B, so'that said head is loose on the axis or pin E and is liable to be lifted and displaced while the spindle is improperly located. To prevent this, I provide the cross bar K, which is connected with said headby means of the screw or pin L, wherebysaid cross-bar may be turned so as to extend parallel with said head or in the position at a right angle thereto, it being noticed that the portion of the body of the shuttle at the adjacent sides of the channel or opening occupied by the head C has offsets or shoulders M thereon, on which the ends of the cross-bar K are adapted to bear, whereby the spindle B is restrained from being lowered when in operative position, thus positively preventing dis connection of the spindle from the axis or pin E. Should it, however, be desired to remove the spindle, the cross-bar K has a quarter-turn imparted to it, whereby it clears the offsets or shoulders M and occupies a position parallel with the head 0. Now the spindle is thrown down by the action of the spring G, and the back of the head 0 rises, when the head may be raised by hand clear of said pin and so removed therefrom, thus occasioning the removal of the spindle from the shuttle.

In order to rest-ore the spindle, the head 0 is reapplied to the body A from the under side thereof, the slot D being in somewhat vertical position, so as to pass over the pin E, after which said head is lowered on said pin and the spring G and bearing-piece F are applied in position so as to bear against the head when the spindle is raised into the body A. The cross-bar is again turned at a right angle to the head 0, so that its ends overhang the shoulders M, thus preventing the disconnection of the head from said pin, while, however, allowing the proper motions of the spin= dle with the bobbin or cop-tube thereon. It will here be noticed that the upper wall of the recess D is extended in the direction toward the bearing-piece F, so as to form the tongue D Now in restoring the spindle-head in position as above stated the adjacent limb of the piece F enters the recess D so that when the spindle is raised said tongue freely overhangs said limb and places the piece in its normal position, said piece and head forming a knuckle, as most clearly shownin Fig. 3, the same causing the piece to yield in the subsequent out and in motions of the spindle, while the tongue prevents upward disconnection of the piece, the pressure of the piece being directed on the head, as is evident.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. In a shuttle, a spindle-head and a rotatable locking device therefor, said device being adapted to be placed in the transverse and longitudinal directions of the body of the shuttle for respectively permitting and positively preventing the removal of the spindle.

2. In a shuttle, a spindle-head having a lock thereon, the same being adapted to be turned on said head whereby said head may be engaged with and disengaged from the body of the shuttle.

3. A shuttle provided with a spindle-head and a shoulder at a side of the latter, and a cross-bar mounted on said head and adapted to be turned so as to overhang said shoulder and be removed therefrom.

4. In a shuttle, a spindle-head, a body provided with a shoulder at a side of said head,

a cross-bar pivotally mounted thereon, andan axial pin, said head having an open slot adapted to receive said pin and said bar be- 7 said shanks in which said head has its move- 7 ments.

7. In a shuttle, a spindle-head pivotally mounted on the body of the shuttle and having a recess in its baok,and a spring-pressed piece adapted to enter said recess, the upper wall of said recess projecting so as to freely overhang the adjacent portion of said piece.
